From 0105d2b4fbc24c2fb6ca9bae650784dd7ddf0b12 Mon Sep 17 00:00:00 2001 From: Daniel De Graaf Date: Mon, 28 Nov 2011 11:49:10 -0500 Subject: [PATCH] xen/gntalloc: release grant references on page free gnttab_end_foreign_access_ref does not return the grant reference it is passed to the free list; gnttab_free_grant_reference needs to be explicitly called. While gnttab_end_foreign_access provides a wrapper for this, it is unsuitable because it does not return errors.
